Description

  

  Nutisolation für elektrische Maschinen.    Es ist bekannt, die     Nuten    elektrischer  Maschinen mit Hülsen aus Isoliermaterial  auszukleiden.<B>Als</B>     Isoliermaterial    verwendet  man vorzugsweise Pressspan, Lackleinen,     Mi-          kanit    oder dergl. Derartige Nutisolationen       haben:    keine besonders hohe     thermische     Festigkeit, mit Ausnahme des Mikanits, für  den aber die Beschaffung des Glimmers       Schwierigkeiten    macht.

   Die Erfindung hat  ,die Aufgabe, eine dem Mikanit ebenbürtige,  auch thermisch widerstandsfähige     Nutisola-          auch    thermisch widerstandsfähige Nutisola  tion zu schaffen.  



  Erfindungsgemäss besteht die Nutisola  tion aus einem Trägerstoff mit aufgeklebten  Glasfolienschichten. Der Trägerstoff kann  aus Papier oder Gewebe bestehen.     Legt        man.     auf hohe thermische     Festigkeit    Wert, dann  verwendet man     mit    Vorteil anorganische Pa  piere und Gewebe, z. B. Glasgewebe, und  hoch     wärmebeständige        Bindemittel,    z. B.

         hitzebeständige        Kunstharze    oder     anorga-          nische        Bindemittel.       Die Erfindung soll an Hand !der in -den  Fig. 1 bis 4 dargestellten Ausführungsbei  spiele näher erläutert werden.  



  Fig. 1 zeigt eine im Profil U-förmige  Nutenhülse, deren Wände aus zwei     Papier-          schichten:    1 und     einem        dazwischenliegenden     Stapel von Glasfolienteilen 2 bestehen. Die       einzelnen.    Teile     sind    durch     Klebelack    oder  dergl. fest miteinander verbunden und durch  Pressen und Erhitzen in die U-Form ge  bracht.  



  Fig. 2 zeigt im wesentlichen die gleiche  Ausführungsform, jedoch sind hier die     Rän-          ,der    der     Hülse    eingeschlagen.  



       In        Fig.    3     ist    eine geschlossene Hülse     ,dar-          gestellt.    .       Unter        Umständen    kann,     wie        Fig.    4 zeigt,  ,der     Innenraum    der     Hülse    durch     U-förmige     Einsagen in einzelne     Wickelräume    aufgeteilt       sein.     



  Die     Erfindung    ermöglicht     die    Herstel  lung     einer    dem     Mikanit    ebenbürtigen, hoch-      wertigen Nutisolation, die ohne Schwierig  keiten     mindestens        teilweise    aus dem in     ge-          nügenden    Mengen zur     Verfügung        stehenden          heimischen        Glas        hergestellt    wird.



  Slot insulation for electrical machines. It is known to line the slots of electrical machines with sleeves made of insulating material. The insulating material used is preferably pressboard, enameled linen, micanite or the like. Slot insulation of this type does not have particularly high thermal stability, with the exception of micanite but for whom the procurement of the mica makes difficulties

   The invention has the task of creating a thermally resistant Nutisola and thermally resistant Nutisola tion that is equal to the micanite.



  According to the invention, the Nutisola tion consists of a carrier material with glued-on glass film layers. The carrier material can consist of paper or fabric. If you lay. value for high thermal strength, then one uses with advantage inorganic paper and tissue, z. B. glass fabric, and highly heat-resistant binders, e.g. B.

         heat-resistant synthetic resins or inorganic binders. The invention is to be explained in more detail with reference to the exemplary embodiments shown in FIGS.



  1 shows a groove sleeve with a U-shaped profile, the walls of which consist of two paper layers: 1 and a stack of glass film parts 2 lying in between. The single ones. Parts are firmly connected to one another by adhesive varnish or the like and brought into the U-shape by pressing and heating.



  Fig. 2 shows essentially the same embodiment, but here the edges of the sleeve are hammered.



       In Fig. 3, a closed sleeve is shown. . Under certain circumstances, as FIG. 4 shows, the interior of the sleeve can be divided into individual winding spaces by U-shaped inserts.



  The invention enables the production of a high-quality slot insulation which is equal to the micanite and which is produced without difficulty at least partially from domestic glass that is available in sufficient quantities.
